Abstract

A voltage converter circuit includes a high side transistor, a high side driver coupled to a control input of the high side transistor, a low side transistor coupled to the high side transistor at a switch node, and a current steering circuit coupled to the control input of the high side and to the switch node. During transition of the high side transistor to an on state, a current from the high side driver initially divides between the control input of the high side transistor and the current steering circuit, and as a voltage on the switch node increases, less of the current from the high side driver flows through the current steering circuit and more of the current from the high side driver flows to the control input of the high side transistor.
